Noise Level Monitoring & Testing

Noise Level Standards Limits or noise level standards defined by pollution control board during Day time for Residential Noise < 55 dB and Limits during Night time for Residential Noise < 45 dBIn industry, there are of two types Sound Monitoring & testing or Noise Level Measurement:Ambient Noise level MonitoringIn-plant Noise level Monitoring A) Ambient Noise level standards Ambient Noise level Monitoring or Noise pollution Measurement within industrial zone at ambient conditions. (e.g. Near Main Gate, Near Canteen, Near Manufacturing plant etc.) As per Central Pollution control Board (as per Factory act 1948): Limits or acceptable noise level during Day time for Ambient Noise < 75 dB and Limits during Night time for Ambient Noise < 70 dB. B) In-plant Noise level Standards In-plant Noise level means Sound level measurement allocated in the plant.As per Central Pollution control Board (as per Factory act 1948) Limits for In-plant Noise level < 90 dB.
